* HiDeep Finger and Stylus touchscreen controller
Required properties:
- compatible : must be "hideep,hideep-ts"
- reg : I2C slave address, (e.g. 0x6C).
- interrupts : Interrupt to which the chip is connected.
Optional properties:
- vdd-supply : It is the controller supply for controlling
main voltage(3.3V) through the regulator.
- vid-supply : It is the controller supply for controlling
IO voltage(1.8V) through the regulator.
- reset-gpios : Define for reset gpio pin.
It is to use for reset IC.
- touchscreen-size-x : X axis size of touchscreen
- touchscreen-size-y : Y axis size of touchscreen
- linux,keycodes : Specifies an array of numeric keycode values to
be used for reporting button presses. The array can
contain up to 3 entries.
Example:
#include "dt-bindings/input/input.h"
i2c@00000000 {
/* ... */
touchscreen@6c {
compatible = "hideep,hideep-ts";
reg = <0x6c>;
interrupt-parent = <&gpx1>;
interrupts = <2 IRQ_TYPE_LEVEL_LOW>;
vdd-supply = <&ldo15_reg>;
vid-supply = <&ldo18_reg>;
reset-gpios = <&gpx1 5 0>;
touchscreen-size-x = <1080>;
touchscreen-size-y = <1920>;
linux,keycodes = <KEY_HOME>, <KEY_MENU>, <KEY_BACK>;
};
};
